Proctor Over Fascia Vent FV10 BAL

The Proctor over fascia vent FV10 BAL is a 10mm x 1000mm eave vent with BAL mesh pre-fitted, built to draw air into the roof space between the sarking and the fascia board on steeper roofs. It delivers 10,000mm² of positive airflow per linear metre, which is the intake size a traditional pitched roof over 16 degrees needs. The pre-fitted BAL mesh adds ember protection for bushfire-prone areas while keeping the same airflow as the standard FV10.

Key Features

• 10,000mm² positive airflow per linear metre, 1/300 ratio
• 1000mm length for a continuous eave run
• Pre-fitted BAL mesh for ember protection
• Reduced height profile, no need to pack out roof sheets
• 4mm openings sized to block large insects and prevent capillary action
• Compatible with timber and metal fascias

Specifications

• Product: Proctor over fascia vent FV10 BAL
• Size: 10mm x 1000mm
• Airflow: 10,000mm² per linear metre, 1/300
• Design: traditional roofs with pitch over 16 degrees
• Openings: 4mm evenly spaced
• BAL: pre-fitted BAL mesh

Installation

The FV10 BAL fits between the fascia and the cladding at the eave, with the openings facing the roof space. The reduced height keeps the vent discreet on the fascia, and the flutes give a clean surface for fixings. On a steeper roof the 10mm intake is the right size for the air volume the roof space needs, so match it to the pitch rather than defaulting to the larger FV25.

Applications

• Eave ventilation on traditional roof pitches over 16 degrees
• Bushfire-prone areas where a BAL-rated eave vent is specified
• New builds and re-roofing with a calculated ventilation system
• Roofs where a low, discreet fascia vent is wanted

What You Need To Complete The Job

The FV10 BAL is the inlet, so it works with an outlet at the ridge. Pair it with a Proctor ridge vent RV10 BAL for a matching bushfire rating, and use the standard Proctor FV10 where BAL is not required. See the Roof Ventilation range for the full system.

Frequently Asked Questions

When should I use the FV10 BAL?

Use it on steeper roofs over 16 degrees where the eave intake needs to be 10,000mm² per linear metre, and where the build needs ember protection. The BAL mesh keeps embers out of the roof space through the vent.

What is the airflow on the FV10?

It delivers 10,000mm² of positive airflow per linear metre, which is a 1/300 ventilation ratio. The FV25 moves more air at 25,000mm² per metre and suits lower pitches. Match the intake to the roof pitch so the roof space gets the air volume it needs for its size.

Does the BAL mesh reduce the airflow?

No. The BAL version keeps the same 10,000mm² airflow as the standard FV10. The mesh is sized so it stops embers and debris without choking the vent.

Does it fit metal fascias?

Yes. The FV10 BAL is compatible with timber and metal fascias, so it works on modern metal fascia lines as well as traditional timber eaves.

Does the BAL mesh need cleaning?

The ember mesh is fixed and requires no regular maintenance. Check it during roof inspections and clear away any leaves or debris that collect over the vent openings. The mesh is sized so it stops embers and insects without choking the airflow.
